    Yes, big torque bump. I have not revved it past 8Krpm yet, but it is so cool to be able to do smooth throttle wheelie's in a predictable manner with the added torque now. This morning for the first time I took the interstate to work and pinned the throttle briefly in 6th gear and was just amazed how fast I went from 70 to 100mph before letting off (don't want to rev past 8k rpm yet, nor pay the speed tax). It is now an "almost" no compromise street SuMo with the power to easily pull the tall gearing (75mph is a leisurely ~5700 rpm), and still a wet weight below 300lbs.

    You get everything you need with no exchange. Kit comes with piston, rings, wrist pin, circlips, factory cylinder, and upper and lower gaskets.

    Agreed, if you are going to tear into it, there is no reason NOT to go big. The original stuff was in great condition with no wear, but I didn't know that until I tore into it, and besides it was a good excuse to upgrade. The cost to go big bore can't be much more than to replace with stock size stuff, so to me it was a no-brainer. Plus it was a fun project and I got to see the insides of the engine for the first time ever.

    I have everything to put it back to 501cc at any time. The Husky Manual recommends full rebuild at 6000 miles even for street ridden bikes in restricted form, so I did it to be safe, as the bike was immediately put into power-up mode and has had lots of high rpm usage (15hr rebuilds are recommended for race usage and I figure I fall somewhere in the middle).

    I tore down the valve train and measured the contact areas as per the manual, and everything was good there too. The rod bearing was solid with no play, and everything in the valve train that requires lube showed no signs of wear either. Use 10w-60 like you are supposed to, let the engine warm up before BRAAP'ing on it, and the motor shows no wear after 6000 miles of hard use!

    The Pistal big bore piston was 22g heavier than the original (285gr vs 307gr) but the balance of the engine is fine, with no vibes. I did take a jewelers file to put a radius on the sharp corner cut into the valve clearance on top face of piston to help reduce pre-ignition sources, but otherwise the detailing that went into the Pistal is amazing. Every possible nook and cranny was machined away for no excess weight without sacrificing strength. As a machinist in a former life, I was very impressed with all of the detail that was taken to process the webbing on the backside of the piston, in our current climate of cheap Chinese crap, where everyone has useless jobs and no one has any useful skills yet don't understand why there are no jobs, it was all the more impressive to see something that took effort and skill to make, and was done well.

    I thought that exact thing when I put a lovely Omega piston in my CCM in order to make it a 710 from a 644cc (it was a shame to bury it inside an engine), well it certainly didn't want to stay inside the engine for long, as a short time afterwards something let go and caused a catastrophic engine failure at Mac1 down a dual track overtaking a HGV:censored:
    Still wouldn't put me off big boring the Husky mind:thumbsup:

    Wow I really want one of these! It maybe become a winter project if the winter budget opens up a little! I have a 2005 510 that has been in the garage most of its life until I bought it. Anyway it is very low hours. So here is my question. Would I be ok to just drop one of these in without a thorough brake down inspection of my bike? Would that just be a recipe for Kaboooom?


    sorry about my last post. I got confused with two manufactures it has been deleted!

    A bit of metal filler and a file and everything was as good as new:thumbsup:

    Sorry for the hijack, but I thought others may be amused at my past misfortune;)

    Agreed... I am almost sure I went from low to mid 50's whp to upper 50's whp, with a LOT more torque. To get that last couple HP on top of the full 530RR adds close to $3000 for the head and cams, whereas the biggest gain can be had for a little more than $500.

    $3500 for 62hp or
    $525 for ~58hp

    Cost/Benefit the 532cc kit is a clear winner whereas the RR head is just about impossible to justify for a street ridden bike. I am willing to bet the RR head is actually poorer performing in the midrange and definitely in the low end where you spend most of your time anyway. Up top, no contest the RR is most definitely preferable... unless it is your own money:p

    And trust me, I wrestled with it and tried to rationalize getting the 530RR head but then found a used Aprilia SXV550 with Akra and PC map that puts out 70whp (have dyno run for this one) for a track bike for not much more money. Somehow buying an entire bike with more power than the Husky could ever dream to put out for about the same cash seemed to make more sense. :thumbsup:

    Torque monster SM530R for commuting and street riding, and SXV550 for the racetrack is the best of both worlds. Though there is something to be said for the simplicity and the sheer fun factor of the 530RR thumper over the swiss watchmaker with Italian quirks 550SXV twin.

    Yeah looks ugly... hopefully the Pistal won't do the same! But with all the torque, no need to explore the rev limit anyway. :D

    It WAS the 644cc (710cc as you see there, well what's left of it)Suzuki lump found in the CCM range or suzuki Freewind.

    Wilmar mate, sounds like you are well pleased with the outcome, and I've got to agree with you in relation to the 530RR. If you want to race on the track and be competative(and have the dosh) then yes the RR is needed, but for the average rider on the road, then the standard 530 has to be the best "Bang For Buck" mod you can do. Especially for you lot in the States, as over here in good old Blightly the conversion is a whole heap of money more than what you paid:confused:

    Motosportz, Would the 530 kit work on the 05-07 510's as well?

    For the amount you lot pay in the States, I'd defo' go for the 530, we pay the same in pounds as you do in dollars and have to give our original barrel in exchange!!
    The only difficulty compared to the Dfi bikes will be the setup being a tad more tricky. After all the PCV and Autotune alters the fueling for you rather than the jetting and dyno work required for the carbed bikes

    Ya jetting is a pain in the butt. I figure I have to jet the high compression as well.

    Yes it will fit your 510. I think the next step would be full Titanium exhaust, or the RR model Ignition, theres also a cam, and even a full RR model head. Go to your husky dealer and ask to look at the special parts catalogue. Lots of stuff for your bike in there.
